Abstract
With a view to providing an X-ray imaging apparatus having a projector-collimator capable of adjusting an irradiation position of a light beam easily and accurately, a first luminous flux is made a luminous flux present within an orthogonal plate orthogonal to a y-axis direction which is an orthogonal direction and a second luminous flux present within the orthogonal plane is reflected and moved within the orthogonal plane to produce a light beam. Consequently, an irradiation position of the light beam over a subject can be adjusted in an independent manner by movement Δy in the orthogonal direction with use of a first screw and movement Δx within the orthogonal plane with use of a second crew. As a result, adjustment of an X-ray irradiation field position by an operator can be effected not only easily but also with a high accuracy.
